Don't get me wrong, Firefox Quantum is great. Everything's smooth, looks great, except for one thing: after upgrading, all my tabs were lost. That's all good, and I don't start freaking out until my sessionstore.js file doesn't work. Other than renaming my previous.js to sessionstore.js and moving it to my main profile, is there something I should be doing?

Mozilla has really screwed up for a lot of people with this update which has wiped out all of our open tabs and disabled Session Store.
